Features

Standard 80-meter tensile and wear-resistant cable

The whole vehicle is equipped with 80 meters of tensile and wear-resistant cable as standard, and the cable is automatically retracted and released to achieve flexible and fast equipment entry and exit.

Seven-series high-strength aluminum alloy beam

The propulsion beam adopts a seven-series high-strength aluminum alloy beam, and the single drilling depth can reach 4.5m, which meets more construction requirements.

Hydraulic transmission

Adopting hydraulic transmission, electronically controlled power shifting without stopping, more convenient control and more stable performance

High-power rock drill

Equipped with high-power rock drill, fast drilling speed, low drilling tool consumption and low failure rate
